Core promoter is a lecture and an article as part of the gene transcription series.

You are free to take this quiz based on the core promoter at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the {{gene project}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz[edit]

Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

dispersed promoter
proximal promoter
downstream promoter
distal promoter
enhancer
focused promoter

2. Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed


3. True or False, Some core promoters are located in the distal promoter.

TRUE
FALSE

4. Which of the following is not a transcriptional characteristic of core promoters?

located between nucleotides -8 and +2 relative to the transcriptional start site (+1)
G/A/T-G/C+1-G-T/C-G-G-G/A-A-G/C
in eukaryotes
TATA-less genes
a consensus sequence

5. Complete the text:
